Glorious Gardens from Above: Cornwall

SYNOPSIS

New series. Horticulturist Christine Walkden embarks on a journey to explore some of the most impressive gardens in the UK - from a hot-air balloon. In the first edition, she hovers above Cornwall, and finds herself overwhelmed with nostalgia by the giant Brazilian gunnera. Later, she meets a man whose own childhood was spent playing in the garden, before testing her nerves at St Michael's Mount.

Host: Christine Walkden
